Transmission not working properly?

hello, so, i have an odd Transmission problem. here we go, so i backed the car out of my driveway and went to drive away made it quarter of a mile down the road maybe and it lost all gears. no noise no slipping. engine remained running but could not grab a gear. shut it down and restarted no problems and no gears. had it towed home changed ATF was red-ish brown. did not smell burnt. with fluid change no abnormal metal chunks. i have replaced the two sets of solenoids and the engine speed sensor. Ohmed out the main and counter shaft speed sensors they fall within the range as stated in the Honda Service manual. The car now will grab a gear when it starts. It will not hold the gear all the time though. When it drops the gear, now you have to shut the car down and wait 5 min and restart to get it to get a gear. help please
